Detailed Description

The invention will be described in detail below with reference to the accompanying drawings, wherein for the purpose of illustrating embodiments of the invention, the drawings showing the structure of the device are not to scale but are partly enlarged, and the schematic drawings are only examples, and should not be construed as limiting the scope of the invention. It is to be noted, however, that the drawings are designed in a simplified form and are not to scale, but rather are to be construed in an attempt to more clearly and concisely illustrate embodiments of the present invention.

As shown in fig. 1, 2 and 3, the material extracting tool of the present embodiment includes a suction cup 1, a suction cup holder 2, an exhaust piston 3, a handle connecting holder 4 and a handle 5. Sucking disc 1 sets up in the bottom of sucking disc seat 2, has a sealed chamber 2a in the sucking disc seat 2, sealed chamber 2a and sucking disc 1 intercommunication, and the top of sucking disc seat 2 is provided with one and the air vent 2b of sealed chamber 2a intercommunication, and air vent 2b communicates with each other with the sucking disc seat outside. Handle connecting seat 4 sets up on sucking disc seat 2, and fasteners such as its accessible screw, rivet link to each other with sucking disc seat 2, also can adopt threaded connection's mode to link to each other between handle connecting seat 4 and sucking disc seat 2. The handle connecting seat 4 is a hollow pipe body. The handle 5 is arranged on the top of the handle connecting seat 4.

The exhaust piston 3 of the present embodiment is disposed in the handle connecting seat 4 and can reciprocate along its own axial direction. One end of the exhaust piston 3 protrudes upwards from the top of the handle connecting seat 4, and the other end of the exhaust piston passes downwards through the vent hole 2b of the sucker seat 2 and extends into the sealed cavity 2a of the sucker seat 2. The bottom end of the exhaust piston 3 has a sealing portion 3a, and the outer diameter of the sealing portion 3a is at least larger than the inner diameter of the vent hole 2b, so that the vent hole 2b can be blocked. The outer diameter of the seal portion 3a may correspond to the inner diameter of the seal cavity 2a, and the effect of closing the vent hole 2b can be similarly achieved. The present embodiment is provided with a push button 6 on top of the venting piston 3. Be provided with reset spring 7 between button 6 and sucking disc seat 2, outside exhaust piston 3 was located to reset spring 7 cover, reset spring 7 provided a power that upwards resets for exhaust piston 3, made exhaust piston 3 have the trend of rebound all the time when not receiving other exogenic actions, the sealed portion 3a of exhaust piston 3 pastes the roof of tight seal chamber 2a to the realization is to the shutoff of air vent 2 b. An air inlet hole 4a is arranged on the side wall of the handle connecting seat 4. The sucking disc of this embodiment adopts silica gel to make, except sucking disc and spring, other parts adopt engineering plastics to make. In order to facilitate the assembly of the exhaust piston, the suction cup holder 2 of the present embodiment is composed of an upper holder body 2-1 and a lower holder body 2-2. In order to avoid air leakage, a gasket (not shown) may be provided between the contact surfaces of the exhaust piston 3 and the seal chamber 2 a.

The following describes the method of use of the present embodiment:

When a worker holds a material taking tool to pick up an electric core, a sucker 2 is lightly pressed on the electric core to enable the sucker 2 to be tightly attached to the surface of the electric core, after no gas or little gas exists in the sucker 2, a pressure difference can be formed between the inside and the outside of the sucker under the action of external atmospheric pressure, a partial vacuum state can be formed at the contact position of the sucker and the electric core, the electric core can be adsorbed by the sucker under the action of the formed pressure difference, for example, the sucker with the diameter of 12mm is taken as an example, two suckers can adsorb about 0.7kg of heavy objects under normal atmospheric pressure, and the weight of one electric core is about 0.09 kg; the workman will be with electric core removal to the turnover dish in, when will putting electric core, the workman gently presses button 6 at handle connecting seat 4 top for exhaust piston 3 overcomes reset spring 7's elasticity and moves down, and the sealed portion 3a of exhaust piston 3 leaves the roof of seal chamber 2a, and air vent 2b is opened, and the air that gets into in handle connecting seat 4 from inlet port 4a can get into behind seal chamber 2a from air vent 2b and get into in sucking disc 2, and the suction of sucking disc is relieved, and electric core falls into in the turnover box. Therefore, damage to the battery cell when the battery cell is directly pulled out from the sucker can be avoided, the influence of human uncontrollable factors on a product in the material taking process is reduced, the product yield is improved, and the material taking efficiency is improved.

Certainly, the technical concept of the present invention is not limited to the above embodiments, and many different specific schemes can be obtained according to the concept of the present invention, for example, in the above embodiments, in order to facilitate the worker to hold the material taking tool by hand, the suction cup seat is provided with the handle connecting seat and the handle, but the handle connecting seat and the handle can be omitted, at this time, the vent hole is directly communicated with the outside, and the upper end of the exhaust piston only needs to extend out of the suction cup seat, and the effect of ventilation or sealing can also be realized; under the condition of having the handle connecting seat, the air inlet hole can be arranged on the side wall of the handle connecting seat and also can be arranged at the top of the handle connecting seat; the button is a convenient, but not essential, component for the pressing of the vent piston; the exhaust piston can also be provided with a spring abutting part, for example, the exhaust piston is provided with a protruding part protruding out of the side wall of the exhaust piston, one end of a return spring abuts against the spring abutting part, and the other end abuts against the sucker seat; in addition, in the foregoing embodiment, the return spring is disposed outside the sealing cavity of the suction cup holder and sleeved on the exhaust piston, but the return spring may also be disposed in the sealing cavity and abutted between the sealing portion of the exhaust piston and the bottom of the sealing cavity; such modifications and equivalents are intended to be included within the scope of the present invention.
